Tip end bracket

Abstract

A mounting bracket device and method for mounting a blade of a wind turbine to a transportation device are disclosed. The mounting bracket device includes a clamping device for holding the blade, an adjustment system, and a connecting system adapted for being removably connected to the transportation device. The connecting system removably connects the clamping device and the adjustment system to the transportation device. The adjustment system is adapted to align the clamping device with respect to the transportation device around the first rotary axis and around a second rotary axis.

Description

FIELD OF INVENTION[0001]The present invention relates to a mounting bracket device for mounting a blade of a wind turbine to a transportation device. Moreover, the present invention relates to a method of mounting a blade of a wind turbine to a transportation device.ART BACKGROUND[0002]In modern times, energy is produced more and more by regenerative energy sources, such as wind turbines. In order to increase the efficiency of wind turbines, blades of the wind turbines are getting larger and larger. When increasing the size of the blades of the wind turbines, the transportation of the blades from the fabrication location to the location of operation is getting more and more complex.[0003]Transportation of a wind turbine blade is done by trucks, trains or ships. Thus, by transporting the blades by these conventional transportation means, the available space for transportation is restricted by the environment, i.e. when transporting a blade by train or by truck the blades have to be f...

AI Technical Summary

Benefits of technology

[0014]By using the mounting bracket device, an adjustable and flexible transportation device for a blade of a wind turbine may be provided, so that the mounting bracket device is adjustable and flexible to different ways of transportation Thus, the blade may be transported in a safer way, so that damages of the blade during the transportation may be avoided. The connecting system of the mounting bracket device provides a connection for truck, rail and sea transport devices without any changes in the design of the mounting bracket device itself. Furthermore, the adjustment system of the mounting bracket device provides a way of adjusting the blade in different angle positions around at least two rotary axes, so that, depending on the way of the transportation, desired angle positions may be adjusted. Thus, a flexible adjustment around two rotary axes may be provided, so that an improved alignment to a variety of different restrictions of different transportation devices may be provided. Furthermore, by using the connecting systems adapted for being removably fixed to the transportation device, it is possible to clamp the blade with the clamping device at the location of fabrication and the mounting bracket device is fixable to different types of transportation devices without the need of taking the blade out of the clamping device.

[0027]According to a further exemplary embodiment, the clamping device comprises a transport opening. The transport opening is adapted for receiving a strap lashing for fixing the blade. Thus, the blade may be wrapped by the strap lashing or a belt in order to provide a further fixation means of the blade to the mounting bracket device. By providing a transport opening at the clamping device, the strap lashing may be fixed to the mounting bracket device, so that no further connections at the transportation device are necessary. Thus, a change of the transportation device is eased.

Problems solved by technology

When increasing the size of the blades of the wind turbines, the transportation of the blades from the fabrication location to the location of operation is getting more and more complex.

Thus, by transporting the blades by these conventional transportation means, the available space for transportation is restricted by the environment, i.e. when transporting a blade by train or by truck the blades have to be fit to conventional tunnels or allowable heights in order to fit under it, for example.
